This has confined the bearing portion to the length of the runner which is to the rear of said braces, and there- .fore somewhat limited the lateral curve of the runner which is in contact with the ground when bent laterally. In the present form of my invention the runner does not commence to bend upwardly to meet the side bars until substantially the point indicated by A in the figures of the drawingsis reached, from which point the runners then bend upwardly in a gradual curve for slightly over half the height of, the sled, at which point a sharp bend is made, as indicated at 16, so that the runner extends slightly rearward and then is bent the forward portion of the runners which are connected with the body of the sled. This may be illustrated in the following way: Taking, for instance, a sled in which the total length of each runner is thirty-six inches, the bearing-surface at the rear of the forward,

- supports inthe previous forms of sleds having bendable runners amounted only to about twenty-one and one-half inches, whereas in the form of sled herein described the bearingsurface has been extended to approximately twentyreight inches. Furthermore, in the ,previous designs of sledsof this character the length of the flexible portion which is in contact with the snow or ice amounted only to about nine inches, whereas in the present form the bearing portion which may be laterally bent is substantially sixteen inches or that indicated between the lines A and B in the drawings. It will therefore be seen that by this construction not only is a greater bearingsurface given, to the runner, which will prevent the samefrom sinking into the snow to such an extent as heretofore, but also that the bearing portion of the runner which is in contact with the ice or snow is made bendable for a much greater portion of its length, and therefore more nearly conforms, to the arc of a circle which the whole runner should assume in order to theoretically cause the sled to traverse exactly a curved path,

It will be seen that various changes may be made in the form, arrangement, and proportion of the parts of the construction herein described without departing from the spirit and scope of my invention; but What I claim, and desire to protect by Letters Patent of the United States, is-

1. In a sled having flexible runners, a ran nor which curves gradually upward from a point intermediate the forward runner-support and the forward end of the sled providing a maximum bearing-surface for the flexi ble portion,-substantially as described.

2. In asled havingflexible runners,arunner which curves gradually upward from a point intermediate the forward runner-support and the forward end of the sled, and then sharply rearwardly to connect with the body of the sled, thereby providing a maximum bearing-surface for the flexible portion, substantially as described. 3. In asled having flexible runners, forward supports which are r'novably related to the forw'ard portion of the body of the sled, the runners of said sled being curved'gradually' upward from a point intermediate said foF ward supports and the forward end of the sled, and therefrom being sharply curved to connect with'the forward end of the body of the sled. r a

4. In a sled having fiexible'runners, forward supports which are adapted to move transversely in relation to the body of the sled, the

runners of said sled being curved gradually upward from a point intermediate said forvward supports and the forward end of the sled, and then being curved rearwardly and connected with the body of the sled, thereby providing a maximum hearing-surface for the flexible portion and allowing the runner to curve transversely to a point in the rear of said forward support.

5. In combination with a sled havingflexible runners, a runner T-shaped in cross-sec tion which curves gradually upward from a point intermediate the forward runner-support and the forward end of the sled providing a maximum bearing-surface for the flexible portion, substantially as described.

6. In combination with a sled having flexi ble runners, a runner T-shaped in cross-section, forward supports which are adapted tov move transversely in relation to the body of the sled, the runners of said sled being curved gradually upward from a point intermediate said forward support and the forward end of I the sled, and then being curved rearwardly and connected with the body "of the sled, thereby providinga maximum bearing-sub face for the flexible portion, and allowing the runner to curve transversely toia point in the rear of said forward support.
